Greetings,
A function aborts with the error in the subject line despite the available free space on the disk.
I have a bunch of other questions regarding the underlying reason but first things first: why is pg telling me no space is left on device when there is space?

the only config param I can see relevant to this is temp_file_limit which I've set to -1, but it made no difference. How can I make sure that as long as there is disk space available, I don't get this error?

Regards
Seref
